Trireme has three peaks and was named for its resemblance to the Greek style of warship. The western peak is the highest and was the first to be climbed, from the Agnes Glacier. A traverse of all three peaks involves some time-consuming ridge climbing.

---|---|---|---|---|---|---|---|
AG | AGFrom Agnes Glacier, West Pk | ||||||
Climb direct from the glacier. The route of the first ascent. |

South East Ridge, West Pk | |||||||
First climbed along the summit ridge from the middle peak during a traverse of all three of Trireme’s peaks. |
|||||||
South West Ridge, Middle Pk, 2 | 2 | 0m | |||||
From Veil Bivouac, head up Veil Stream and follow the Clover Glacier to gain the ridge at the prominent col between the Middle Peak and Helmet Peak. An easier route may be to climb direct to Orb Col from the junction of Veil Stream and the Havelock River, and then sidle Helmet Peak on its north side. Depending on conditions, either choose a route from the small glacier west of the peak or follow the north-west side of the South West Ridge on generally good rock.
